This may have been around for ages, but we're only just seeing it thanks to the guys over at CHUD.com. It's a trailer for the new documentary It Might Get Loud, directed by Davis "An Inconvenient Truth" Guggenheim and starring The Edge, Jimmy Page and Jack White.
The idea of the film is that three, representing different eras of electric guitar playing, meet up swop ideas, maybe jam a little. If you need more, you probably aren't a big fan of guitar music.
The film doesn't yet have a UK release date, but is out in Germany and the US in August so fingers crossed that we'll see it soon after that. If it's even a fraction as good as the last great rock doc, we'll be there with bells on.
